Keep Dancing, Lizzie Chu

A girl tries to cheer up her grieving, forgetful grandfather by taking him on a rollicking road-trip adventure in this charming and poignant middle-grade novel
  
Twelve-year-old Lizzie Chu has lived with her Wai Gong (grandfather) in Glasgow since her parents died when she was a baby. But Wai Gong has been acting different lately. He spends a lot of time talking to his Guan Yin statue—the Chinese goddess of compassion, kindness, and mercy—at his altar and seems to be becoming more forgetful. Even the shared passion he and Lizzie have for their favorite show, Strictly Come Dancing, seems to be tailing off.

When Lizzie’s friend Chi visits one day dressed as Princess Leia for Comic Con, Wai Gong mistakes her for Guan Yin, and is naturally delighted, and Lizzie seizes the opportunity to use Chi as Guan Yin to help her with her grandad. And then Lizzie gets an idea: she and Chi can take Wai Gong to Blackpool to the Tower Ballroom, where he’d always dreamed of going. If only she can get her grandad there, she thinks, he’ll find some peace, and perhaps things will be OK at home again. After all, one of the myths around Guan Yin is that she brings order and harmony, so it’s got to work out—right?
